APPARATUS FOR MAKING ICE.

Be it known that I, DAvn) J. HAVEN- s'rm'ra, a citizen of the UnitedStates, residing at Newark, in the county of Essex and State of NewJersey, have inventedcertain I new and useful Improvements in Apparatusfor Making Ice, or which the following is a specification.

The invention consists in apparatus for producing ice in blocks ofdefinite dimensions ina tank containing the body of water to be frozen,by simultaneously and independently freezin fractions of said body-ofwater, each included in a separate cell disposed within said'tank andhaving its walls independent of the tank walls.

The apparatus includes broadly a tank, a plurality of molding cellshaving walls independent of the tank Walls, and refrigerating meansdisposed within the space bounded by the walls of each cell.

The invention further consists in the con-' struction, whereby the iceblock may be thawed off from each cell, and in the various combinationsmore particularly recited in the claims.

In the accompanying drawiir sFigure 1 is a plan view of the left hancIsection and Fig. 2 is a plan view of the right hand section of the tankz'so that if Fig. 2-be placed to the right of Fig. l the whole tank inplan 7 is shown; In Fig. 2 the headers 6 and connections are removed. Inthe two series of cells at the left the ice blocks are shown formed. Inthe'two series of cells on the right, the bottom plates are broken awaytothe line 4 4 of Figsl and 2: Fig. 5 shows,

tubes, parts being broken away and in seca-n the connections for fluidsupply. Fig.

.Similar characters of reference indicate like parts.

A is a tank containing. the water to be frozen 'here divided into twosections by the vertical partition B. Sup orted above the bottom of thetank by suitable blocks are any desired number of horizontal planks C,extending parallel to one another transversely across the tank. Uponeach plank is laid the horizontal portion of a pipe coil Specificationof Letters Batent. Application filed July 1, I908. Serial No. 441,379.

Patented Nov. 2, 1909.

D, the turns of which are separated by wooden strips, which support theinetalfbot- .tom plate E. Near-the-ends of each plate are rising platesF which extend upward,

I nearly to the top of the tank. In the space between the plates F andthe wall of the plates F and similarly extending upward.

Between the several pairs of metal plates G,

H, are. pipe coils I shown in F ig. 4:. The

turns of these coils are horizontal and parallel, and they extend acrossthe intervals between the pairs of plates G, H, supported on the severalplates E. In said intervals said coils are supported by vertical bars Jplaced on opposite sides and bolted together.

,The upper ends of all the coils I in the left hand section of the tank(Fig. 1) are connected to a-heacler K and the lower ends to a header L.Similarly in the right hand section the upper ends of the coils l areconnected to a header M, and the lower ends to a header N all of theseheaders K, L, M, N, being supported within the tank A.

It will be seen that by-this construction 1 have provided within thetank a plurality of series'of mold cells, each cell having a bottomformed by the horizontal plate E and two sides formed by the risingplates. Thus to illustrate in Fig. 3: the plate F, the plate G and somuchof plate E as lies between plates F-and G; form one cell. Similarly,the plate H, of one pair-G, H, the plate G of the next pair G, H, and somuch of the plate E as lies between said plates 11, Gr, form anothercell, and so on. And it will be further observed, that in proximity toand outside ,of the plates forming these cells lie the pipe coils l) orI, as the case may be.

Now, in each of these cells 'I produce, by the means to lie described, aseparate ice block, and thaw it free from the cell by the circulation ofwarmjliquidthrough the coils l) and I. The number of cells which may bemade above each transverse plate E, is immaterial. Thus in the drawings,I show four. The number of series of cells is also immaterial; In Figs.1 and 2, taken to-' So that in' the whole which an ice block may beformed.

v in longitudinal supporting bars 7.

- immaterial.

1 will now describe the means for freezing Y plpes the water to producesaid blocks in said cells.

Extending above each series of four cells is a header (5, preferablyseated at its ends From 1 each header (Fig. (5) downwardly extend asmany groups of tubes 8 as there are cells in a series. Thus in Fig. 3:the header 6 has four groups of tubes 8. and one gro n of tubes enterseach cell, the lower ends 0 the tubes extending nearly to the bottomplate E. The number of tubes in each group is I here show four.

The tubes 8 are closed at their lower ends, and within them are smallertubes 9, open at both ends. The header 6, Fig. 5, is made in twosections threaded at their ends to receive collars 10. Between saidcollars is S65 cured a partition 11, having an internally threadedcentral sleeve 12, which receives the threaded ends of the two sectionsof a horizontal pipe 13, the opposite ends of which pipe sections'areclosed. the horizontal pipe 13. So that i'iuid entering header (5, bypipe 14, fills the left hand section of the header, passes dow'ntl'irough the lefthand group of four tubes 8, rises through the internaltubes 9 to horizontal pipe 13, thence passes down-through the right handgroup of four tubes 8, rises through their internal tubes 9 to the righthand section of header (5, whence it escapes by pipe 15.

I will ow describe the connections and the general operation of theapparatus. The

headers 6 being put in place, with the several groups of depending tubesin the several cells, refrigerating liquid, delivered from any suitablesource to a header 0 suitably supported outside of the tank (Figs. 6 and7), passes by pipes 16 to pipes 14, and so to the headers 6, andinto.,the freezing tubes 8. Ice is then formed upon each of said tubes8. in a gradually thickening layer or cylinder. These several cylindersmeet, and ultimately an ice block is formed, as already stated, fillingeach cell. After passing through the tubes 8, the refrigeratin liquidpasses by pipe 15 to pipe 18 to hea er P outside of the tank (Fig. 3),and so to any desired outlet. After the iceblocks are formed in theseveral cells, they are thawed off. free from the cell 'the tank.

surfaces by, warm-liquid circulated in coils D and I, from the header R,to a similar header (notl shown) on tho qaposite side of The tubes 9enter i l i and through coils D, are as follows: by to coils D to ipes26, Fig. 3, and opposite header. If esired, refrigerating thud may beled through coils D and I, from header 0. The connection from header 0to and through coils D is by pipes 27 to coils D and by pipes 28 toheader P. The connection t'rtgm header O1 to and througisthe coils I, isie 29, *ig. 7, to ipe to header K tli rd ugh coils I, to header L, andby pipe 30 to pipe 23.

Suitable valves are provided in the several pipes in order to establishthe aforesaid connections with the headers. After the ice blocks arethawed clear of' the cells, the

the tubes 8, are lifted out of their seats, and

. said headers, tubes and blocks, aretransported to any place where itmay be desired to "free the blocks from the tubes. To this end,couplings 31 of any suitable description, between the pipes 15 and 18,and i6 and 14, are disconnected. The blocks are then thawed from thetubes 8 by connecting the pipe 14 with any suitable source of warmliquid supply, so that said liquid may circulate through said tubes andescape at pipe 15.

[t' itbedesired to turn warm liquid into the tubes 8, to release themfrom the ice block in order that they may be removed leaving said blockin the'tank, this is accomplishcd by means of the pipe 32 connectingheader. .l.t and pipe to, Fig. T, and pipe 33 connecting pipe to withthe opposite header, Fig. 3.

Theusual pipe for drawing oil water .trom the tank is shown at 34.
